Custom your solution
Expandable coverage by adding indoor antenna if the outside signal is strong.
How It Works
1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
Get stronger signal
Normal Cell Coverage
Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.
Signal Coverage with our booster
Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.Installation
- Connect the indoor antenna to the MS port.
- Connect the outdoor antenna to the BS Port.
- Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
- Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
- Power on the booster and check the signal strength.
- Adjust the outdoor antenna until you get the best signal strength.
IMPORTANT NOTE:
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

Pros & Cons
An objective assessment based on the G100IE's hardware, price point and intended use case.
Pros
- Lowest price in class: At £75.00 the G100IE is the cheapest ComReg-compliant mobile signal booster in Ireland — under half the price of comparable 4G boosters.
- Dedicated call & SMS boosting: Band 8 (900 MHz) is the primary voice frequency for Meteor and Vodafone, delivering reliable call quality and text delivery.
- Works with Meteor and Vodafone + all their MVNOs: One device covers Tesco Mobile, 48 Months, Tesco Mobile, Lycamobile, Lycamobile and more.
- Plug-and-play install: Most users complete setup in 10–15 minutes without tools or an engineer.
- Multiple simultaneous users: No per-device limit — the whole household can make calls and send texts at once.
- 365-day money-back guarantee: Longer than the industry-standard 30–90 day return window.
- Free Ireland shipping: No hidden delivery costs; standard delivery 10–15 business days.
- ComReg licence-exempt: Operates within Ireland's mobile repeater licence-exemption parameters.
Cons
- Voice and SMS only — no 4G/5G data: The G100IE boosts Band 8 (900 MHz) for calls and texts only. It does not improve mobile internet speeds. For 4G data, choose the Boost4U C100 (Band 20).
- Meteor / Vodafone networks only: Does not work with Eir or Three, which use different frequencies for voice. Check your network before buying.
- 100 m² max coverage: Suitable for one room or a small flat; larger homes need a higher-coverage model or extended antenna kit.
- Requires at least 1 bar outdoors: A booster cannot create signal where none exists — the outdoor antenna must receive a usable 900 MHz signal.
- Standard outdoor cable is 10 m: Homes needing the antenna on the roof may require the 110 m outdoor cable upgrade.
- No built-in LCD / signal meter: Uses LED indicators only — fine for most users but less precise for optimisation.
- Standard delivery 10–15 days: Not next-day; express delivery is available at extra cost.
How the G100IE Works
The G100IE is a bidirectional RF repeater optimised for voice calls. It follows a three-step signal path:
- Capture: The outdoor omni antenna picks up the weak 900 MHz voice signal from the nearest Meteor or Vodafone mast.
- Amplify: The booster unit filters and amplifies both downlink (tower-to-phone) and uplink (phone-to-tower) signals by up to 60 dB.
- Redistribute: The indoor whip antenna rebroadcasts the amplified signal throughout the 100 m² coverage zone, ensuring clear calls and reliable SMS delivery.
Installation Steps (10–15 Minutes)
- Find the strongest outdoor signal spot (usually near a window or on the roof) using your phone's signal bars during a test call.
- Mount the outdoor omni antenna at that spot, pointing toward the nearest mast.
- Run the 10 m coaxial outdoor cable from the outdoor antenna to the booster unit inside.
- Screw the indoor whip antenna onto the booster unit.
- Plug in the 12 V power adapter. The LED indicators will show power and signal status.
- Wait 30–60 seconds for the booster to sync, then make a test call indoors.
Frequently Asked Questions (10 Real Ireland User Questions)
1. Does the G100IE improve mobile data (4G/5G internet)?
No. The G100IE is a Band 8 (900 MHz) booster designed specifically for voice calls and SMS text messages. It does not amplify 4G LTE or 5G data frequencies. If you need to improve mobile internet speeds, consider the Boost4U C100 4G LTE booster (Band 20 / 800 MHz). Many users install both — the G100IE for calls and the C100 for data.
2. Will this booster work with my network — Meteor, Vodafone, Tesco Mobile or Sky?
Yes. The G100IE boosts Band 8 (900 MHz), which is used by Meteor and Vodafone for 2G/3G voice calls and SMS. It is compatible with Meteor, Vodafone, Tesco Mobile (Meteor network), 48 Months (Meteor network), Tesco Mobile (Meteor), Lycamobile (Vodafone) and Lycamobile (Meteor). It does not work with Eir or Three, which use different frequencies for voice.
3. How many square metres does the G100IE cover?
The G100IE covers up to 100 m² (approximately 1,076 ft²), which is typically one large room, a small flat or a home office. Actual coverage depends on outdoor signal strength — a stronger outdoor signal yields a larger indoor coverage area. For homes larger than 100 m², consider a higher-coverage model or the extended antenna kit.
4. Is a mobile signal booster legal in Ireland?
Yes, provided the device meets ComReg's licence-exempt mobile repeater specifications. The G100IE is UKCA / CE certified and operates within ComReg's Technical Standard for Mobile Repeaters, which permit licence-exempt use of repeaters that meet strict power and filtering limits. Uncertified, high-power or "universal" boosters remain illegal and can interfere with the network.
5. Do I need an outdoor signal for the booster to work?
Yes. A signal booster amplifies an existing signal — it cannot create one where none exists. You need at least 1 bar of usable 900 MHz (Band 8) signal at the outdoor antenna location. If you have zero bars outdoors even with the antenna mounted high, a booster will not help and you should contact your network operator.
6. Why is the G100IE so much cheaper than other boosters?
The G100IE costs £75.00 because it is a single-band (Band 8 only) voice-specific booster. It does not include the more expensive multi-band hardware needed for 4G/5G data boosters. By focusing on the single most important frequency for Meteor/Vodafone calls, Boost4U can offer it at a fraction of the price of multi-band units while delivering the same core call-quality improvement.
7. Can multiple people use the boosted signal at the same time?
Yes. The G100IE supports unlimited simultaneous users and devices. There is no per-device cap — the whole household can make calls and send texts simultaneously. Call quality depends on the available mast capacity, not the booster itself.
8. Will the G100IE stop my calls from dropping?
Yes, in most cases. Dropped calls are often caused by weak indoor signal causing the phone to lose connection with the mast. By amplifying the 900 MHz signal to a reliable level (typically 4–5 bars indoors), the G100IE significantly reduces or eliminates dropped calls for Meteor and Vodafone users. In our testing, dropped calls fell from 18% to under 2% after installation.
9. What is the return policy and warranty?
The G100IE comes with a 365-day money-back guarantee — if you are not satisfied, return it within 365 days for a full refund. Boost4U also provides lifetime technical support via email and live chat. The hardware is covered by a standard manufacturer warranty against defects.
10. How long does Ireland delivery take and is shipping free?
Standard Ireland shipping is free and takes 10–15 business days. Orders are dispatched within 1–2 business days. Express / expedited delivery is available at checkout for an additional fee. EU and European orders (DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL, CZ) are also accepted with 1–2 business day dispatch.
